Detailed Description
DisplacementControl is a subclass of StaticIntegrator, it is used to when performing a static analysis on the FE\_Model using the displacement control method. In the displacement control method the displacement at a specified degree-of-freedom Uc is specified for each iteration. The following constraint equation is added to equation~\ref{staticFormTaylor} of the StaticIntegrator class:
where 
depends on 
, the displacement increment at the previous time step, 
, the number of iterations required to achieve convergence in the previos load step, and 
, the desired number of iteraions.
is bounded by 
and

This is a pure virtual method, one must be written for each instantiable subclass of MovableObject. Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through {theChannel}. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using {theBroker}. To return 
if successful or a 
if not.

This is a pure virtual method, one must be written for each instantiable subclass of MovableObject. Each object has to send the data needed to be able to reproduce that object in a remote process. The object uses the methods provided by {theChannel} object to send the data to another channel at the remote actor, the address of the channel is set before this method is called. An object of similar type at the remote actor is invoked with a {receiveSelf()} to receive the data. Returns
if successful (successful in that the data got to the channel), or a
if no data was sent.
